User Guide: PicoC

This site is a really first beginning.

During startup I will collect german information that I translate a little bit later. But for me it's easier to do it this way ;)

Sorry.

Enable PicoC

• ModuleSettings
• AdminState
  • PicoC = Enable

First Test

PicoC in Interactive-Mode

• ModuleSettings
• PicoCSettings
  • Startup = OnBoot
  • Source = Demo

Serial Port

USB_VCPPort = PicoC In this case you have a virtual serial parallel to you normal USB for GCS If Source = Demo you see a counter written to you terminal. If this is ok, change Source to File and save the settings.

Scripts

Howto put a script to you board

goto

• Data Objects
• PicoCStatus
  • Command = USARTmode

Goto to your terminal and enter Ctrl-A you should get start of heading as answer. If yes, your terminal work well. On windows Putty didn't work for me. I use Tera Term. You have the following commands in USARTmode:

• CTRL-A: Clear buffer, pointer to zero
• CTRL-B: Open buffer, all input goes to the buffer now
• CTRL-C: Block buffer, save pointer. Ctrl-B enable writing again
• CTRL-D: Block buffer, pointer to zero
• CTRL-E: read out the whole buffer

To write a file to the buffer, use this stepps:

1. Ctrl-A
2. Ctrl-B
3. Copy your source to clipboard
4. Send Clipboard to board (Ctrl-V in terminal)
5. Ctrl-C
6. Ctrl-D

now you can check the buffer with Ctrl-E. You should now see your source!

• Data Objects
• PicoCStatus
  • Command = SaveFile or Idle

Should save the file to the flash or simply end the USARTmode.

Following some example scripts.

Sonar HC-SR04

• PPM+PWM+ADC
• OUT5 = Trigger,
• IN2 = Echo

#include "system.h"
#include "pwm.h"
PWMFreqSet(2,10); /* set channel 5-6 to 10Hz */
PWMMinSet(5,0);   /* set channel 5 Min to 0 */
PWMValSet(5,10);  /* set channel 5 to 10µs pulse */
while (getchar() != 27) {
 float distance = PWMValGet(1)/58.0;
 printf("Distance = %f cm\n", distance);
 delay(500);
}

Sinus-LED via Accessorychannel

• Out5---470R---LED---GND
• GCS Output: Channel 5 set 0 to 20.000 and neutral to 10.000
• MixerSettings / Mixer5Type / Accessory0

#include "system.h"
#include "math.h"

int main() {
 sync(0);
 float f = 0;
 while (!armed()) {
  AccessoryValSet(0,sin(f));
  f=f+0.1;
  printf("%f\n", sin(f));
  sync(20);
 }
 AccessoryValSet(0,-1);
 return 0;
}

exit(main());
